can someone please help me :) marking as brainlest

1) Z = 3.17

2) 4.69  or √22

3) X = 42°

4) X = 60°

Step-by-step explanation:

1) (4)(8+4) = (Z)(Z+12)

48 = Z² + 12Z

Z² + 12Z -48 = 0

(Z +15.17)(Z - 3.17) = 0

Z = 3.17

2) (2)(11) = Y²

y² = 22

Y = 4.69  or √22

3) 180° - 139° = 41°

41° = 1/2(40° + X)

41° = 20° + 0.5X

21° = 0.5X

X = 42°

4) X = 1/2(240°-120°)

X = 1/2(120°)

X = 60°
